About products and suppliers

UPS is a self-activating enhanced battery system that serves as a primary power source in case of a power disruption. It also allows users to shut down electronic devices safely. A UPS power supply prevents electric fluctuations and helps keep consistent power levels. However, it has several designs providing different protection. The UPS power backup has varying capabilities and sizes, depending on the type and measurement of the protected equipment, city, or building complex. People often interchange backup batteries and uninterruptible power supply, but these systems work differently. A backup battery works only during an outage to allow users to shut down devices safely.

Types of UPS

A UPS power supply for the home can be the standby or offline type that offers battery backup using a DC/AC inverter output. However, it doesn't provide continuous power during surges and sags. Therefore, this home UPS power supply is suitable as a backup for personal computers and small office workstations.

A UPS power system can also be line-interactive, providing electricity for 30 minutes tops. If it has an expansion, it can work many hours using a variable-storage, multi-tap autotransformer. This UPS power source is appropriate for devices that require moderate protection during fluctuations. Lastly, a double-conversion online system works similarly to a line-interactive. However, it has a rectifier driving a DC/AC inverter and protects critical UPS power-only loads from power interruptions.

Uses of UPS

A power backup system provides business continuity during brownouts by protecting critical and sensitive equipment. It also protects against power spikes, power sags, under-voltage, over-voltage, noise interference, harmonic disruptions, switching transients, and frequency fluctuations. UPS power systems help manage risks for manufacturing, information technology, and healthcare facilities by providing electricity continuously in case of power fluctuations or disruptions. Sometimes, it takes a long time to start an emergency generator; therefore, a battery backup provides power immediately to prevent devastating consequences to several industries. In addition, a small UPS power supply should provide the proper protection level to a critical resource in case of outages and interruptions.
